Description

The purpose of this study is to investigate the effect of spray-spray interaction on the entrainment mechanism in diesel combustion field. In this paper, the ambient air flow is measured with laser induced fluorescence and particle image velocimetry (LIF-PIV), and the backflow arrival distance is used to understand the ambient air flow. The interaction region between sprays is estimated from the geometric relationship of the sprays in the multi hole nozzle case, and the indicator of influence by the spray-spray interaction on the entrainment mechanism is proposed. The correlation between the experimentally measured backflow arrival distance and the theoretically calculated degree of the influence by spray-spray interaction on the entrainment mechanism was investigated, and the effectiveness was evaluated.
